/*************************************************************
 * sqltypes.h
 *
 * This is the lowest level include in unixODBC. It defines
 * the basic types required by unixODBC and is heavily based
 * upon the MS include of the same name (it has to be for
 * binary compatability between drivers developed under different
 * packages).
 *
 * You can include this file directly but it is almost always
 * included indirectly, by including.. for example sqlext.h
 *
 * This include makes no effort to be usefull on any platforms other
 * than Linux (with some exceptions for UNIX in general).
 *
 * !!!DO NOT CONTAMINATE THIS FILE WITH NON-Linux CODE!!!

 * I (Nick) have made these changes, to cope with the new 3.52 MS
 * changes for 64 bit ODBC, but looking at MS's spec they havn't
 * finished it themself. For example, SQLBindCol now expects the
 * indicator variable to be a SQLLEN which then is a pointer to 
 * a 64 bit value. However the online book that comes with the 
 * headers, then goes on to describe the indicator_ptr in the 
 * descriptor record (which is set by SQLBindCol) as a pointer
 * to a SQLINTEGER (32 bit). So I don't think its ready for the
 * big time yet. Thats not to mention all the ODBC apps on 64 bit
 * platforms that this would break...
 *
 * I have just discovered that on win64 sizeof(long) == 4, so its
